- Update 08.2026 - 14 August 2026
🌴 Update 08.2026 🌴 Hello everyone, Today, we would like to give you a small update on our current projects. This way, you can find all the important information at a glance, and we can present our news together instead of sending many individual messages. Of course, there is also a little bit of marketing involved 😉. We apologize for that and thank you for your understanding. Summer Islands Over the past few weeks, we were able to collect even more feedback. A big thank you goes to Kinichie, with whom I conducted a three- to four-hour playtest. This feedback, along with additional comments from DoKomi, your emails, and directly from the Steam forums, led me to the decision to focus intensively on fixing bugs over the next month and release an update. We still have a larger content update planned, but I do not want to wait until then to fix the existing bugs. We also want to reintrodu…

- Summer Islands Update 1.0.4 - 28 March 2026
Polishing Your Islands – Update 1.0.4 Hello everyone, with Update 1.0.4, we mainly focused on many small and large issues that were affecting your experience in the game. This update is primarily about bug fixes, stability, performance, and overall polish. ⛰️ Terraforming with Undo Function We fixed several issues related to terraforming. You can now also undo changes as long as the game is paused – including a direct refund of your money. 📷 Camera issues fixed After loading, the camera no longer starts somewhere in the void, but at the spot you were looking at last. Camera movement is now also more performant. 🖥️ Better display on different resolutions Issues with image centering, scaling, and special screen formats such as 3840x1200 (32:10) have been fixed. 🔠 Better readability The font was difficult to read in some places – we improved that.

- Blog post: 2024 summary and outlook for 2025 - 25 December 2024
Hello everyone, We wish you a relaxing Christmas again this year. We hope you, your family and your friends are all well. Thank you very much this year for your support and also the nice and interesting conversations at all the game festivals we visited this year. It was really fun and a real win for Summer Islands and us!!! It's not long now until the full release of Summer Islands on 25.01.2025 The last few weeks have been a bit hectic, alternating between the relaxed feeling of “Easy Going” and “WE WILL NEVER DO THIS!!!! AAAHHHH” We were able to implement a lot. All the construction sites and TODOs are currently on the home straight. The biggest construction sites have been completed and the campaign is ready for fine-tuning. The biggest “nice-to-have” tasks are still the languages and making the whole thing compatible with the Steam deck again after all the changes from the last few…
- October 2.Update 2024 [v0.9.6] with announcement & bug fixes - 20 October 2024
Hello everyone, Well... you're probably wondering “The next update was supposed to be the full release, right?” Yes, it will be ... Moved ;) Yes, we wanted to feel like the big development studios and delay our release for a while. But for us it's only 1 month. Planning for the full release is now 25.01.2025 The reasons for the shift are as follows: 1. there were more bugs for the last release than expected (I would like to apologize to everyone for the bugs and thank you for your help). 2. the day job requires more “overtime” in the next few weeks and another exhibition in mid-November and the XMas madness comes right after that. 3. the strongest reason is: The release number of further games in December is enormous. Let me explain that a bit. Whoever publishes their game on Steam usually has a goal to make their game better known. This doesn't always have to be the case, but there is…
- October Update 2024 [v0.9.5] with several improvements - 9 October 2024
Hello everyone, Yay, the time has finally come. The new update v0.9.5 is here and it has a lot of feedback from the last few months and also from Gamescom. First, I'd like to briefly outline the new features and then talk about the coming months. You had to wait a long time. I have to admit, I personally found the updates every 1-3 months in the last few years a bit more relaxed, because every player wants to see the changes/improvements. If it all comes months later, then you might as well put the game aside for a year or so :D Well. This update was also planned a little earlier. But with hobbies, you're always dependent on your day job or vacations or whatever. Well, let's get to the features. We change the entire code with every update. Therefore, a lot of “under-the-hood” has happened again. But let's move on to the things that you actually notice. From the game events, e.g. Gamesco…

- After Gamescom 2024 and update v0.9.5 - 29 August 2024
Hello everyone, Gamescom is over and I wanted to write a little review here for you. For everyone who couldn't/wouldn't attend or for everyone who would like to know something about the numbers. Gamescom ran from Wednesday 21.08 to Sunday 25.08. On Wednesday 21.08 the press and streamers were allowed to see everything (and private visitors who bought an extra ticket from 1 pm) On 22.08 and 23.08 all halls were open On 24.08 and 25.08 the business halls were closed. All other halls for private visitors were open. The Indie Arena (Hall 10.2) is intended for an indie game like Summer Islands. There were several options here every year. The largest area is the Indie Arena Booth. You apply for this and a jury evaluates whether a game is selected or not. Then you pay a 4-digit amount fee according to how much space you want. Alternatively, there is Home of Indies. Here you can simply buy a pl…

- June Update 2024 [v0.9.4] with engine upgrade and much more - 7 June 2024
Hello everyone, The time has finally come. Thank you very much for your patience. In this update everything has been turned upside down again and due to the long time a lot could be changed. The update was basically ready two weeks ago. Then came the Indie Game Fest and some things were adjusted again. To be honest: fortunately!!! There were still a few bugs and a few errors in thinking. But the Indie Game Fest was great fun. Looking over the shoulders of so many people as they celebrate the game and give feedback is really great. Thank you all for your feedback! Alright, enough of the past. Let's take a look at the hot s***. The main feature in this update is the engine upgrade. I.e. 30-60fps until the late game. We were able to verify this in some long-term tests. Nevertheless, everyone has different hardware, which is why there will always be deviations. A lot of under-the-hood adjus…
